Learn Typography by Building a Nutrition Label

The instruction says I should span the 20% and make it bold and align it right as well that which I have done but I keep on getting error.

<p class="dbl-indent no-divider"><i>Includes</i> 10g <i>Added</i> Sugars
        <span class="bold right">20%</span></p>
        <div class="divider dbl-indent"></div>

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Thank you so much for your support, I appreciate it a lot.
